Clearly, we still have a lot more to learn about the universe: The Large Hadron Collider, famed for its discovery of the Higgs boson, has discovered two new subatomic particles. Known as Xi_b’- and Xi_b*-, the two particles had previously been predicted to exist by the formidable hypothesizing powers of particle physicists, and now they have been observed and confirmed by CERN’s LHCb team.

The Higgs boson machine — CERN’s Large Hadron Collider — is barely five years old, and yet the international group of physicists is already planning its successor. Dubbed the Very Large Hadron Collider (points for creativity), the new collider will be around 60 miles long (four times longer than the LHC), and smash protons together with a collision energy of 100 teraelectronvolts (14 times the LHC’s current energy). While the LHC’s discovery of the Higgs boson was a watershed moment, its existence poses more questions than it answers — and those answers probably can’t be answered by the LHC.
